Carbon Monoxide Detectors and How They Work

Jan 28, 2019· Carbon monoxide detectors trigger an alarm based on an accumulation of carbon monoxide over time. Detectors may be based on a chemical reaction causing a color change, an electrochemical reaction that produces current to trigger an alarm or a semiconductor sensor that changes its electrical resistance in the presence of CO.
